And just eight minutes after replacing Lucas Moura, Spurs took the lead as Christian Eriksen lashed his left-footed strike into the bottom corner.

The win for Tottenham is a major boost in their hopes to finish in the Champions League places, as they now sit three points above Chelsea in fourth.

But it was Dier's reaction to seeing Janssen coming on that sent social media wild, with the England international fiendishly grinning as he slapped his thighs.

Janssen was shipped off on loan to Turkish side Fenerbahce last season, and wasn't even given a squad number when he returned to the club last summer.

But he has forced his way back into first-team contention after shaking off an ankle injury, and will now push for more minutes in the closing stages of the season.

Commenting on Dier's reaction, one fan tweeted: "The gif of Dier getting overly excited over Janssen coming on has probably just made me night. He is just adorable in it."

Another commented: "Get you a friend that is excited for you as Dier is for Janssen."

While one said: "Eric Dier is basically all of us seeing Janssen coming on."
